Signal Long Range™

Up to 300 m (1,000 ft) from the Converge Gateway™: Long Range when embedded in 100mm (4”) of concrete, or up to 72 acres of coverage per Gateway.The range may vary based on site layout, reinforcement density, and environmental conditions.

Yes.

Because the Converge Gateway™: Long range is site-deployable and locally managed, Signal Long Range™ can maintain reliable connections in tunnels, basements, or shielded structures where public networks (like Sigfox or cellular) fail.

Both are fully embedded, cable-free sensor systems.
The key difference is range and attachment design

• Signal (Bluetooth) offers real-time data via Converge Gateway™: Bluetooth or manual collection with a phone.
  
  
• Signal Long Range™ adds Long Range connectivity, giving you automatic real-time data via Converge Gateway™: Long Range or manual collection with a phone.
  
  
• Signal Long Range™ also features a unique proprietary attachment method that makes it even easier to install than any other sensor.

No.

Signal Long Range™ is a single-use embedded sensor, designed to stay permanently in the concrete for the most accurate, continuous data. If you need a reusable option, Helix offers even greater long range connectivity, uses replaceable Thermal Tails™, and reusable nodes.

Signal Long Range™ sensors use digital thermal probes with ±0.5°C accuracy — around three times more accurate than thermocouples, which typically measure ±1.5°C and are not ASTM C1074 compliant. The Signal Long Range™ sensor body itself offers accuracy up to ±0.2°C. This ensures data integrity for real-time strength estimation and thermal control.

Thermal Tails™ are Converge’s modular temperature probes.They connect to Signal™, Signal Long Range™, and Helix^® sensors interchangeably, letting you measure temperature at multiple depths or across large pours.

Each Tail can include up to three probes, with custom lengths available up to 29 m (95 ft).

Yes.

All Converge sensors, Signal™, Signal Long Range™, and Helix^®, feed data into the same ConcreteDNA^® CURE app.

You can combine embedded and reusable sensors to suit each pour, project, or budget. 3 systems, one platform, infinite possibilities.

No problem.

Signal Long Range™ and the Converge Gateway™ store data locally and automatically sync with ConcreteDNA® CURE once a connection is restored.

Your data is never lost, and you maintain full visibility on-site.

All data is available through the ConcreteDNA® CURE mobile and web app. You can view temperature curves, strength predictions, and pour timelines in real time, and export PDF and CSV reports for QA, compliance, and record keeping.

Yes.

All Converge sensors, including Signal Long Range™ and all compatible Thermal Tails™ are fully compliant with ASTM C1074, the global standard for estimating concrete strength using the maturity method.

The Converge Gateway™: Long Range supports multiple power options for total flexibility:

• Mains power for continuous uptime
• Solar panel for off-grid operation
  
  
• Battery pack for mobile or temporary setups
  
  
• 12V vehicle power for uptime on the go

This makes it suitable for even the most remote or complex job sites.

Each Converge Gateway™ can handle hundreds of sensors within its 72-acre coverage area, depending on data frequency and site density.

You can expand coverage by adding more Gateways as your site grows. No network licensing required, unlike products that use networks such as Sigfox.

The rugged IP68-rated casing is designed to withstand harsh jobsite conditions, including full embedment, rebar movement, and heavy vibration.

If a sensor is physically damaged before pouring, simply replace it or contact our industry regarded, world-class customer support team for assistance.
